PATENT FFIGEQ EDUARD LIEBER T, OF BERLIN, GERMANY.

MANUFACTURE OF EXPLOSIVES.

SPECIFICATION forming part of Letters Patent No. 413,070, dated October 15, 1889. Application filed July 10, 1889. Serial No. 317,078. (No specimens.)

-To all whom it may concern:

Be it known that I, EDUARD LI'E ERT, a sub; ject of theKing of Prussia, German Empire,

and a resident of Berlin, Kingdom of Prussia,

German Empire, have invented certain new and useful Improvementsin the Manufacture of Explosive Compounds, of which the followingis a-specification.

. This invention relates to the manufacture of explosive compounds.

' A'great disadvantage of uitro-glycerine and the dynamite produced from thesa ne gensisTsf in theii sensitiveness to blows or shocks atethese defects, various substances have and inthe property which they possess of congealing or solidifying. In order to obviheretofore been added to the glycerinesuch as, for exainple, nitro-benzole. Although nitro-benzole possesses the propenty of rendering nitro-glycerine less sensitive to blows or shocks and of lowering the freezing-point thereof, ithas, on the other hand, the disadvantage of considerably decreasing the explosive force of the nitro-glycerine, and that the stance which, added to nit-ro-glycerine, pre-.

sents all the advantages of nitro-benzole without having the above-mentioned defect-s.

N itro-glyceriue mixed with five per cent. of isoamyl nitrate does not commence to freeze at thirty-five degrees below, zero, its sensitiveness to blows 0r shocks is much less than that of pure nitrq-glycerine, the explosive force is greater than that of purenitro-glycerinc, and, as isoamyl nitrate under certain circumstances is an explosive substance, it will be completely decomposed by the explosion, and the gases produced scarcely differ from those which are produced by the explosion of purenitro gl'ycerino, and are not poisonous,

as are vapors of nitro-benzole. Moreover, isoamyl nitrate is cheaper than nitro-benzole.

A suitable addition to the nitro-glycerine consists of three per cent. of isoamyl nitrate, or more. In lieu of adding isoaniyl nitrate to the prepared nitro-glycerine, an emulsion of glycerine and isoa'myl nitrate or isoamyl alcohol can be nitrated.

hat I claim is- The process of producing a new explosive compound, consisting in adding isoamyl nitrate to the nitro glycerine, or nitrating a mixture containing glycerine with isoamyl nitrate or isoamyl alcohol.

In witness whereof Ihavo hereunto set my hand in presence of two witnesses.
